Introduction: Over the next several weeks you will be investigating the sites below to discover information on graphing linear equations. The material contained in these sites reinforces and extends the topics covered in our textbook. Many of these sites are interactive which allow you to try examples and get instant feedback on whether you are correct or not.

The Coordinate Plane

Discover the components of a coordinate plane

Investigate coordinates of points in the coordinate plane: Graphing Ordered Pairs

Locate the house, move the house. An activity identifying ordered pairs.

Send the robot home.

Slope of a Line

Investigate the following sites to learn about the slope-intercept form of an equation. From the sites you should gain a better understanding of slope and how to use the slope and y-intercept to quickly draw the graph of a line.

Graph using Slope-intercept form of an equation

Find the slope of a line, given two points

View graphs by plotting the y-intercept and applying the slope

Now you graph by applying the slope-intercept method.
